In today’s business environment, where you need to stay reachable at all times, your phone and internet connection are essential work tools. The costs related to your smartphone, landline, and internet subscription can add up each month. The good news? Part of these expenses can be recovered through your tax return. In this article, discover how to optimize the tax deductibility of your telecom expenses.
The place where you carry out your activity directly affects the deductibility of your telecom costs.
Do you have a separate office or professional workspace outside your home?
→ You can deduct 100% of the costs related to the landline and internet connection installed at that location, including VAT.
Do you work fully or partly from home, or mainly use a smartphone or mobile device?
→ You must determine the professional-use percentage of your telecom expenses.
A practical method is to divide your number of working days per week by seven:
1 working day per week → approx. 15% deductible
5 working days per week → approx. 72% deductible
Your monthly subscriptions are not your only telecom-related costs. Technology investments can also offer tax benefits.
Items such as:
smartphones
tablets
computers
are generally depreciated over three years.
